CONSULT-II Function (BCM)AIS004QB
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
1. Turn ignition switch “ON”.
2. Connect “CONSULT-II and CONSULT-II CONVERTER” to the data link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “BCM”. If “BCM” is not indicated, go to Refer to GI-39
, “CONSULT-II
Date Link Connector (DLC) Circuit”
6. Touch “RETAINED PWR”.
BCM diagnostic test item Check item diagnostic test mode Content RETAINED PWR Work support Changes setting of each function.
Data monitor Displays the input data of BCM in real time.

Test Item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in “OFF” position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-II might be stuck if
“RETAINED PWR” is turned to “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWR Rap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps

MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
Work item Description
IGN ON SW Indicates (ON / OFF) condition of ignition switch
DOOR SW–DR Indicates (ON / OFF) condition of front door switch driver side
DOOR SW–AS Indicates (ON / OFF) condition of front door switch passenger side
